Just a couple of days ago I wanted to increase my swap space to 1 GB instead of 512 MB. This way I could finally do an hibernate. Most of the time I wasn't able to because I have 1 GB of RAM and with firefox and thunderbird running it uses a lot.

So what did I do. I installed Gparted to adjust my disks. As you can see further below my swap partition is for my biggest partition. So I had to resize and move my data a bit to the right so I could grew my swap partition. Make sure do this when you have enough time. I took me around 3 hours. The following commands where used. 

apt-get install gparted

Make sure you have unmounted the partition you want to edit, you are also able to do it with Gparted, but it crashed on my machine. So I did it by hand. NOTE: remember the partition you are using.

System > Administration > Partition Editor

Now we are going to create the swap partition.

mkswap /dev/sda5

After this we will use the UUID in the /etc/fstab and in /etc/initramfs-tools/conf.d/resume. Now we are going to reinitialize the ramfs by using this command:

update-initramfs -u

After this has finished you may reboot normally.

Extra information 

The following commands may help you during the way. 

 # fdisk -l

Always backup everything before you get started just in case something should go wrong...

Hey,
That is for every step you take. It doesn't need to be documented
